D. MANNING, OF KALAMAZOO, MICHIGAN mummy BINDER.

Application med August 27:"1928. Serial No. 302,185.

The main objects of this invention are: First, to provide an improved temporary binder or loose sheet holder which is very easily and quickly manipulated in the securin and releasing of the sheets.

econd, to provide an improved loose leaf or temporary binder in which the rear edges of the sheets when bound lie close to the inner side of the back, thereby substantially reducing the width of the binder.

Third, to provide an improved loose sheet or temporary binder having the appearance of a bound ledger or blank book.

Further objects and objectsv pertaining to details of construction and operation will appear from the description to follow.

The invention is clearly defined and pointed out in the claims. v

A device embodying my invention is clear- 1y illustrated in the accompanying drawing,

in which:

Fig. 1 is a perspective view of my im proved Ytemporary binder or loose sheet hol- Fig. 2 is a fragmentary section on line 2-2 of Fig. l.

Fig. 3 is a fragmentary section corresponding to that of Fig. 2 showing one of the binding bars in released position and one of the positions occupied thereby in engagement and disengagement with the posts.

Fig. 4 is a perspective View of the parts of the binder vcommonly formed of metal, on lwhich the binding is applied.

Fig. 5 is a perspective view of the post locking bar or slide.

Fig. 6 is a fragmentary view partially in section on line 6-6 of Fig. 7

Fig. 7 is a detailed transverse view sectioned on line 7--7 of Fig. 6.

' Fig. 8 is a perspective view of one of the binding bars.

Fig. 9 is a detail section corresponding to that of Fig. 2 with the binding bars omitted. Referring to the drawing, I provide a back l'having inturned knuckles 2'at each longitudinal edge thereof. Binding bars 3 are formed of strips of sheet metal folded longitudinally upon themselves to provide longitudinal chambers for the post locking slides 4. These binding bars have outwardly and forwardly projecting pivot arms 5 terminatin in rearwardly turned knuckles 6.

he cover hinge members 7 are also formed of sheet metal and are preferably'angled as shown, that is, the rear portions 8 thereof are outwardly and rearwardly inclined and terminatein inwardly projecting knuckles 9. The knuckles of the binding bars and the cover hinge members are alined and arranged in interposed relation to receive the pintles 10. The covers 11 are secured to the outer ends of the hinge members, the outer binding 12 of the covers being preferably extended "or continued over the back and being common` to both covers.

Owing to the an led or offset hinge members the book has te appearance of a bound ledger or blank book and, further, when the book is opened there is very little tendency for a rocking movement ofthe sheet body.

The sheets shown conventionally at 13 are 1 provided with alined holes 14 to receive the posts 15. These posts have heads 16 at each end. The binding bars have holes 17 therein adapted to receive these heads. These holes 17 are of such size as to permit the binding bars being engaged with and disengaged from the heads of the posts with a swinging movement as is indicated in Fi 3.

The locking slide 4 has keyole slots 18 therein adapted to receive the heads when the enlarged portion of the slots are alined with the openings in the binding bars and to lock the posts when the narrow portions of the slots engage the necks of the posts. The slides are provided with racks 1,9 coacting with pinions 20, the pinions being journalled in the binding bars and having key sockets 21 in the outer ends of their journals.

By inclining the pivot arms the rear edge of the sheet body lies close to the back as is clearly illustrated in Fig. 2. The arms 14. projecting outwardly permit the use of angled hinge members, thereby rendering it possible to obtain the bound book appearance, an advantage of stability when the book is opened.

I have illustrated and described my improvements in one ofthe embodiments which I have found very practical. I have not attempted to illustrate or describe my improvements in other embodiments or adaptations as I believe this disclosure will enable those skilled in the art to embody or adapt my improvements as may be desired.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:

l. In a binder, the combination with a curved back having pivot knuckles at the edges thereof, of binding bars having opposed post openings therein and provided with pivot arms projecting outwardly and forwardly from their rear edges, said pivot arms being provided with pivot knuckles at their outer ends, covers, angled hinge niembers therefor provided with spaced pivot knuckles at their rear edges, said pivot knuckles of said cover hinge members and binding bars being alined with the pivot knuckles of said back, pintles coacting with the alined knuckles, posts having heads at each end, said openings in said bars being of such size as to permit engagement and disengagement of the posts with a swinging movement of the binding bars, and post securing means carried by said binding bars.
